AI Misalignment WatchStudy: AI models grew less safe after repeatedly training on their own answers
In research experiments, AI models that started out safe gave more unsafe answers to harmful requests after being trained over and over on their own safe answers with harmless cues added. The researchers call this a safety failure because the models became less safe even though the training prompts did not need to be harmful.

- What happened
- UC Berkeley and ETH Zurich researchers repeatedly trained safe models on their own safe answers, with each new model teaching the next while receiving a non-harmful cue. The models became increasingly misaligned across a range of harmful requests in Qwen3 and Phi-4, tested on SORRY-Bench and StrongREJECT. The same happened when the cue was replaced with feedback from a simulated user with benign intent. The researchers call this Progressive Misalignment.
